I don't understand it! Can someone explain me?

Question

Why this codes output 10?
a = 1
while True:
a = (a+1)*2
if a >7:
break
print(a)

Answer 1

a=1
goes in the loop
a =(a+1)*2=(1+1)*2=4
now a=4
again it loops.
a =(a+1)*2=(4+1)*2=10
now a=10
since a>7 it breaks the loop and print the value of a which is now 10

Answer 2

After 1st loop
a =(1+1)*2
a = 4
Then second loop
a = 4 (from the 1st loop)
a =(4+1)*2
a = 10

10 > 7, while loop breaks and output is 10.
